Lattice core forming mould

Abstract

A lattice core molding die, comprising an upper die and a lower die that cooperate with each other, a positioning block, a rubber die and an expanded metal are sequentially arranged in the lower die, and the positioning block is provided with a Corresponding to the groove, the rubber mold is provided with a positioning groove with the same size and shape as the steel mesh. Because the present invention adopts rubber as the pressing die, the size and shape of the positioning grooves are the same as those of the flattened steel mesh, the steel mesh is positioned through the positioning grooves, and the friction force between the steel mesh and rubber is used, so that the steel mesh does not move during the pressing process of the hydraulic press. There will be an offset, which is convenient for controlling the uniformity of the core and reducing the influence of human factors.

Description

technical field [0001] The invention is a pressing mould, in particular to a lattice core forming mould. Background technique [0002] Metal sandwich panels are a new class of multifunctional materials that have emerged with the rapid development of material preparation and machining technology in recent years. Widely used in transportation, aerospace, construction, machinery manufacturing, national defense industry and other fields, but mostly adopt foreign technology or introduce foreign products, such as Alusuisse Singer's aluminum honeycomb panels and Midas Aluminum Co., Ltd. hollow aluminum profiles . [0003] The truss sandwich structure is a new type of structure with three-dimensional continuous space, which has better mechanical properties and a wide range of multi-functional design space compared with the above structures. Therefore, the molding technology of the core has become a key step of the sandwich material, and how to improve the uniformity of the molding...

Problems solved by technology

According to relevant reports from CMI (Cellular Materials International, Inc.) in the United States, V-shaped molds are currently used to form cores, but studies have shown that V-shaped molds require high manual technology, and human factors have a greater impact. Because the mold and metal mesh are easy to slide The node offset is generated, which is not convenient for quality control, and there are problems such as difficult positioning, high mold cost, and long replacement cycle in the molding process.
